Regression introduced in 513948735b
by marking the raw SQL column reference feature for deprecation in
Django 4.0 while lifting the column format validation.
In retrospective the validation should have been kept around and the
user should have been pointed at using RawSQL expressions during the
deprecation period.
The main branch is not affected because the raw SQL column reference
support has been removed in 06eec31970
per the 4.0 deprecation life cycle.
Thanks Joel Saunders for the report.
The optimization introduced in 7acef095d7 did not properly handle
deletion involving filters against aggregate annotations.
It initially was surfaced by a MariaDB test failure but misattributed
to an undocumented change in behavior that resulted in the systemic
generation of poorly performing database queries in 5b83bae031.
Thanks Anton Plotkin for the report.

Oracle requires the EXISTS expression to be wrapped in a CASE WHEN in
the GROUP BY clause.

691def10a0 made all Subquery() instances
equal to each other which broke aggregation subquery pushdown which
relied on object equality to determine which alias it should select.
Subquery.__eq__() will be fixed in an another commit but
Query.rewrite_cols() should haved used object identity from the start.

Subquery annotation references must be resolved if they are excluded
from the GROUP BY clause by a following .values() call.

Now that order_by() has expression support passing RawSQL() can achieve
the same result.
This was also already supported through QuerySet.extra(order_by) for
years but this API is more or less deprecated at this point.
Clearing the SELECT clause in Query.has_results was orphaning GROUP BY
references to it.
Thanks Thierry Bastian for the report and Baptiste Mispelon for the
bisect.
Regression in fb3f034f1c.
inspect.getcallargs() was deprecated in Python 3.5 and the Signature
API (PEP 362) has better support for decorated functions (by default,
it follows the __wrapped__ attribute set by functools.wraps for
example).
This prevent having to pass simple_col through multiple function calls
by defining whether or not references should be resolved with aliases
at the Query level.
This required moving the entirety of DELETE SQL generation to the
compiler where it should have been in the first place and implementing
a specialized compiler on MySQL/MariaDB.
The MySQL compiler relies on the "DELETE table FROM table JOIN" syntax
for queries spanning over multiple tables.
OuterRef right hand sides have to be nested, just like F rhs have to,
during the subquery pushdown split_exclude performs to ensure they are
resolved against the outer query aliases.
